Hi, my fish are making rocky, grinding type noises, and only my bigger fish do it. they are goldfish, around 3" long. the noises are quiet, and you can hear them through the glass of my fish tank. what is that?

It is probably your fish sucking up a rock and spitting it back out. My Goldfish do it all the time.
